Pull your hair back so your face is fully visible
Stand in front of a mirror in good lighting
Use a washable marker, lipstick, or a photo to trace your face outline
Compare the width of your forehead, cheekbones, and jawline
Measure the length of your face from hairline to chin
Check whether your face is longer than it is wide
Check whether your forehead is wider than your jawline
Check whether your cheekbones are the widest part of your face
Check whether your jawline is sharp, rounded, or square
Check whether your face is wider at the forehead, cheekbones, or jaw
Match your features to common face shapes: oval, round, square, heart, diamond, oblong, or triangle
Take a front-facing photo and trace the outline for a clearer comparison
Repeat the check a few times to confirm the shape
